Plastics are with limitless numbers of useful characteristics, and colours, and are easy to manufacture. Plastics have major applications in the field of automotive, building constructions, medical devices, electrical and electronics, industrial machinery, Packaging etc, because of the wide spread of plastic use plastic become an integral part of our life. Once the plastic is discarded it becomes waste and it acts as a pollutant. Accumulation of plastic waste in the environment affects human as well as wildlife habitats on earth. The main disadvantage of plastic waste is that it takes around 500 years to decompose. Recycling waste plastic using the pyrolysis process can be beneficial as it converts waste into energy. Pyrolysis is the endothermic irreversible thermochemical degradation and decomposition of complex long-chain organic polymer molecules into units of simple short-chain compounds at temperatures greater than 3000C in the absence of atmospheric oxygen, with or without the application of pressure. The liquid product is oil-like material and has properties similar to diesel as plastics are originally petroleum-based products. To make pyrolysis more effective by using a catalyst which can be lower the temperature and enhance the efficiency of the reaction to produce liquid oil with characteristics of gasoline or diesel.
